New Study Shows How the Brain Responds to Food Cues

A new study set to appear in The Journal Neuroscience illustrates that it is the way the brain responds to food cues when individuals are not hungry that predicts weight gain and that the reasons why people gain weight can be fundamentally different. The way the brain responds while sipping a delicious milkshake can predict […]

Researchers Solve Multiple Sclerosis Puzzle

New research shows that auto-reactive T cells in MS patients produce different types of inflammatory hormones called cytokines than they do in healthy subjects, opening the door to new treatments for the disease. Evidence has long suggested multiple sclerosis (MS) is an autoimmune disease, but researchers have been puzzled because they found the same T […]

Study Shows Extended Space Travel May Warp Astronauts' Brains

A new study from UC Irvine shows that galactic cosmic rays can cause dementia-like symptoms, making extended space trips to locations such as Mars more difficult to accomplish. What happens to an astronaut’s brain during a mission to Mars? Nothing good. It’s besieged by destructive particles that can forever impair cognition, according to a UC […]

Targeting Breast to Brain Metastatic Tumor

Researchers have developed an in vivo imageable breast-to-brain metastasis mouse model. Using real time in vivo imaging and subsequent composite fluorescence imaging, they show a widespread distribution of micro- and macro-metastasis in different stages of metastatic progression. Harvard Stem Cell Institute (HSCI) researchers at Massachusetts General Hospital (MGH) have developed an “imageable” mouse model of […]

Controlling the Thalamus with Dynamic Synapses

Neuroscientists from Brown University show how cells in the brain’s cortex can either stifle or enhance sensory information incoming from the thalamus, thereby allowing it to focus on just some of the many sensory inputs it might choose to consider. Providence, Rhode Island (Brown University) — We consider only some of the sights, sounds, and […]

Scientists Shed New Light on Sensory Neural Development

New research from Yale University sheds light on sensory neural development and possible new ways to identify mechanisms that can repair damage to the central nervous system. Smell is the only sensory system with a back up, which throughout most of adult life forms new sensory neurons that express specific odor receptors. Now Yale researchers […]

Virus Safely Destroys Brain Tumors

New research from Yale University details how scientists used a novel chimeric virus (VSV-LASV-GPC) containing genes from both Lassa and VSV to target and completely destroyed brain cancer without adverse actions within or outside the brain. Brain tumors are notoriously difficult for most drugs to reach, but Yale researchers have found a promising but unlikely […]

New Staining Method to Reveal Circuit Diagram of the Brain

Researchers from the Max Planck Institute of Neurobiology have developed a special staining method that brings the reconstruction of all nerve cells and their connections within reach. Learning, it is widely believed is based on changes in the connections between nerve cells. The knowing which nerve cells is connected to which other nerve cell would […]

Experimental Cancer Drug Restores Memory

New research from Yale University reveals that the experimental cancer drug AZD05030 blocks damage triggered during the formation of amyloid-beta plaques, restoring synaptic connections and memory in a mouse model of Alzheimer’s. Memory and as well as connections between brain cells were restored in mice with a model of Alzheimer’s given an experimental cancer drug, […]

New Finding Dampens Hopes of an HIV Cure

New research from Yale University shows that HIV can establish itself in the brain as soon as four months after initial infection, dampening the hopes of an impending cure for a disease that afflicts more than 35 million people. Within two years of infection, a genetically distinct version of HIV replicates in the brains of […]

Carbon Nanotube Fibers Make Superior Links to Brain

New research from Rice University reveals that carbon nanotube fibers provide a two-way connection with neurons and show promise for treating patients with neurological disorders. Carbon nanotube fibers invented at Rice University may provide the best way to communicate directly with the brain. The fibers have proven superior to metal electrodes for deep brain stimulation […]

Possible Personalized Treatments for More Aggressive Forms of Brain Cancer

New research from Yale University reveals that it may be possible to develop personalized treatments for more aggressive forms of brain cancer. DNA mutations can cause cancer but in some cases, more mutations may mean a better prognosis for patients. A Yale-led comprehensive genomic analysis of more than 700 brain tumors has revealed one such […]

New Technique Could Lead to Long-Lasting Localized Stimulation of Brain Tissue

Using external magnetic fields and injected magnetic nanoparticles, a new technique developed by researchers at MIT could lead to long-lasting localized stimulation of brain tissue without external connections. This video shows a calcium ion influx into neurons as a result of magnetothermal excitation with alternating magnetic fields in the presence of magnetic nanoparticles. Neurons on […]

Cognitive Skills Peak at Different Ages Across Adulthood

New research from neuroscientists at MIT and Massachusetts General Hospital reveals that different parts of the brain work best at different ages. Scientists have long known that our ability to think quickly and recall information, also known as fluid intelligence, peaks around age 20 and then begins a slow decline. However, more recent findings, including […]

Study Shows Connection Between Key Autism Risk Genes

A newly published study from Yale University reveals an important connection between key autism risk genes in the human brain, a major step toward understanding how brain development goes awry in some individuals with the disorder. The research shows that CHD8, a gene that is strongly linked to autism, acts as a master regulator in […]

Study Shows Hunger Neurons also Control Compulsive Behaviors

A newly published study from Yale University shows that in the absence of food Agrp neurons trigger foraging and repetitive behaviors in mice. In the absence of food, neurons that normally control appetite initiate complex, repetitive behaviors seen in obsessive-compulsive disorder (OCD), and anorexia nervosa, according to a new study by Yale School of Medicine […]

Researchers Map Switches That Shaped the Evolution of the Human Brain

New research from Yale University reveals a detailed catalog of human-specific changes in gene regulation and pinpoints several biological processes potentially guided by these regulatory elements that are crucial to human brain development. Thousands of genetic “dimmer” switches, regions of DNA known as regulatory elements, were turned up high during human evolution in the developing […]
